A common cold can trigger pulsatile tinnitus, the rhythmic whooshing or thumping sound in your ear that keeps time with your heartbeat. The connection is the swelling and congestion a cold causes in the nasal passages and Eustachian tubes, which changes pressure in your middle ear and can make you acutely aware of blood flowing through vessels near your ear. In most cases, the sound fades as the cold resolves. But pulsatile tinnitus also has a long list of more serious causes, and knowing the difference between a benign, cold-related episode and a sign of something worth investigating matters.
How a Cold Disrupts the Middle Ear
Your Eustachian tubes are narrow passages that connect the middle ear to the back of the throat. Their job is to equalize pressure on both sides of the eardrum and drain fluid from the middle ear. During a cold, the mucous membranes lining these tubes swell, and excess mucus can partially or fully block them. When that happens, the middle ear becomes a sealed chamber where pressure can drop or rise relative to the outside world, pulling or pushing on the eardrum.
Experimental research has measured this directly. In a study where volunteers were deliberately infected with rhinovirus (the usual culprit behind a common cold), researchers found a roughly 50 percent increase in abnormal Eustachian tube function and a 30 percent increase in abnormal middle ear pressures between days two and seven of the infection, with a gradual return to normal by about day sixteen.1American Journal of Rhinology. The Response of the Nasal Airway, Middle Ear, and Eustachian Tube to Experimental Rhinovirus Infection That timeline matches what most people experience: stuffed ears that feel full or muffled for roughly one to two weeks, then gradual clearing.
When the middle ear is under abnormal pressure or partially filled with fluid, the structures that normally buffer you from hearing internal body sounds lose some of their insulating effect. Blood flowing through the carotid artery, the jugular vein, and the smaller vessels that thread through the temporal bone suddenly becomes audible. The result is a pulsing sound, often louder when you lie down or turn your head to one side, because those positions change venous drainage from the skull.
What Pulsatile Tinnitus Actually Sounds Like
Pulsatile tinnitus is distinct from the steady ringing or buzzing that most people associate with “tinnitus.” It is typically described as throbbing, beating, or whooshing, and it may or may not sync perfectly with your pulse.2BMJ Journals. Assessment and management of pulsatile tinnitus Some people hear it in one ear, others in both. During a cold, you might notice it is louder on the side that feels more congested, because that ear’s Eustachian tube is more blocked and its middle ear pressure is more disrupted.
Clinicians sometimes divide pulsatile tinnitus into “objective” and “subjective” types. In objective cases, a doctor can actually hear the sound with a stethoscope placed near your ear. Subjective pulsatile tinnitus is heard only by you, often because you have become more aware of blood flow through vessels close to the cochlea. Cold-related pulsatile tinnitus is almost always subjective and stems from changes in how sound is conducted through the swollen, pressure-altered middle ear rather than from any new abnormality in the blood vessels themselves.
Why Congestion Makes Blood Flow Audible
Under normal circumstances, the air-filled middle ear and the thin bony walls of the temporal bone do a decent job of absorbing and dampening the sound of blood rushing through nearby vessels. Two things change during a cold that undermine this insulation.
First, negative pressure in the sealed middle ear can pull fluid from surrounding tissues. Even a small amount of effusion in the middle ear changes its acoustic properties, turning it from an air-filled shock absorber into something more like a liquid-filled amplifier for vibrations coming through the bone. Research on the vascular biology of middle ear effusion has shown that inflammatory mediators, including vascular endothelial growth factor, play a role in driving fluid accumulation during ear infections and related inflammatory states.3Wiley Online Library / The Laryngoscope. The role of vascular endothelial growth factor and vascular stability in diseases of the ear A cold-induced effusion does not need to be full-blown otitis media to alter how your ear transmits sound; even a thin layer of fluid can be enough.
Second, congestion throughout the head increases venous pressure. When your nasal passages and sinuses are inflamed and swollen, venous drainage from the skull can slow slightly, engorging the veins and sinuses near the ear. That extra volume of blood flowing at slightly higher pressure through the sigmoid sinus and jugular bulb, both of which sit just behind your ear, produces more turbulence. And turbulence is what creates the sound you hear.
How Long It Typically Lasts
For most people, cold-related pulsatile tinnitus tracks the congestion cycle. It appears a day or two into the cold, peaks when congestion is worst, and fades as the swelling resolves. The rhinovirus study mentioned earlier found that middle ear pressure abnormalities returned to baseline by about day sixteen after infection.1American Journal of Rhinology. The Response of the Nasal Airway, Middle Ear, and Eustachian Tube to Experimental Rhinovirus Infection So if your pulsatile tinnitus is purely cold-related, you can reasonably expect it to settle within two to three weeks.
That said, some colds are followed by a secondary bacterial sinus infection or persistent Eustachian tube dysfunction, either of which can extend the timeline. If your ears still feel plugged or you’re still hearing the pulsing sound more than three weeks after the cold began, it is worth checking in with a doctor. Persistent Eustachian tube dysfunction can sometimes need active management rather than just time.
Managing the Symptom During a Cold
Since the pulsatile tinnitus is downstream of congestion and Eustachian tube dysfunction, managing the congestion is the most direct approach. Nasal decongestant sprays (like oxymetazoline) used for a few days can shrink the swollen tissue around the Eustachian tube openings, though they should not be used for more than about three days to avoid rebound congestion. Oral decongestants and saline nasal rinses also help thin mucus and reduce swelling. Staying well hydrated and using a humidifier at night keep mucus from thickening further.
A systematic review of medical management for Eustachian tube dysfunction in adults found that roughly half of patients with ETD symptoms improved with medical management overall.4PubMed. Medical Management for Eustachian Tube Dysfunction in Adults: A Systematic Review and Meta-Analysis Interestingly, the same review found that intranasal corticosteroid sprays, which many people reach for instinctively, were not particularly effective for chronic cases, improving only a small minority of patients with longstanding symptoms. For the acute, short-lived ETD that comes with a cold, the evidence is more encouraging, because the underlying inflammation is temporary. Techniques like gentle Valsalva maneuvers (pinching your nose and gently blowing to pop your ears) can sometimes equalize pressure momentarily, though they offer minimal lasting benefit.
The pulsatile tinnitus itself can be especially bothersome at night, when ambient noise drops and the rhythmic sound becomes impossible to ignore. White noise machines, a fan, or even a podcast playing at low volume can mask the sound enough to help you fall asleep. These measures do not treat the cause, but they reduce the distress of hearing your own pulse for hours on end.
When the Sound Points to Something Else Entirely
The reason pulsatile tinnitus gets taken seriously by clinicians is that it has a long differential diagnosis, and some of the causes are vascular conditions that need treatment. A cold-related episode is benign and self-limiting. But if the sound appeared before the cold, persists long after you recover, or has no connection to an upper respiratory infection at all, the underlying cause may be structural or vascular rather than inflammatory.
Pulsatile tinnitus can be broadly classified by where the sound originates: arterial, venous, or arteriovenous.5PubMed Central. Pulsatile tinnitus: imaging and differential diagnosis Venous causes are the most common. These include abnormalities in the sigmoid sinus and transverse sinus, an unusually high or dehiscent jugular bulb, and enlarged emissary veins near the ear.6PubMed. State of the Art: Venous Causes of Pulsatile Tinnitus and Diagnostic Considerations Guiding Endovascular Therapy In these cases, blood flowing through a narrowed or unusually positioned vein creates turbulence that the cochlea picks up through bone conduction.7PLOS ONE. Resolution of Pulsatile Tinnitus after Venous Sinus Stenting in Patients with Idiopathic Intracranial Hypertension
On the arterial side, atherosclerotic narrowing of the carotid artery is a well-known cause, as is fibromuscular dysplasia, a condition where the walls of an artery develop abnormally. In rare instances, pulsatile tinnitus results from turbulent flow within the internal carotid artery due to stenosis in the portion of the artery that runs through the petrous bone, right next to the middle ear.8PubMed Central. Disappeared pulsatile tinnitus related to petrous segment stenosis of the ICA after relief of the stenosis by stenting Even rarer are cranial dural arteriovenous fistulas, abnormal connections between dural arteries and venous sinuses that create a direct shunt of blood.9PubMed Central. Cranial dural arteriovenous fistula as a rare cause of tinnitus – case report Some of these conditions are detectable because a doctor can actually hear the pulsing sound when they listen with a stethoscope near your ear.
The Idiopathic Intracranial Hypertension Connection
One condition that sits at the intersection of pulsatile tinnitus and congestion-like symptoms is idiopathic intracranial hypertension, or IIH. People with IIH have elevated pressure of the cerebrospinal fluid surrounding the brain, and pulsatile tinnitus is one of the hallmark symptoms. In one study, about three-quarters of IIH patients reported pulsatile tinnitus.10PubMed. Persistence of pulsatile tinnitus in patients with idiopathic intracranial hypertension following resolution of papilledema IIH is far less common than a cold, and it typically presents with headaches that worsen with straining, visual disturbances, and sometimes double vision. But a person with early or mild IIH might notice only the pulsatile tinnitus and a vague sense of head pressure, which could easily be mistaken for sinus congestion.
What makes IIH-related pulsatile tinnitus particularly stubborn is that it does not always resolve even when other signs of the disease improve. In the same study, roughly 61 percent of patients who had pulsatile tinnitus continued to experience it even after their papilledema (swelling of the optic nerve, a key marker of IIH) had resolved.10PubMed. Persistence of pulsatile tinnitus in patients with idiopathic intracranial hypertension following resolution of papilledema Researchers have debated whether the pulsatile tinnitus in IIH is driven directly by the high intracranial pressure or by associated structural changes in the venous sinuses. One study found that while structural changes like sigmoid sinus diverticulum and transverse sinus stenosis are more common in IIH patients overall, they were not more prevalent specifically in IIH patients who had pulsatile tinnitus compared to those who did not.11PubMed Central. Sigmoid Sinus Diverticulum, Dehiscence, and Venous Sinus Stenosis: Potential Causes of Pulsatile Tinnitus in Patients with Idiopathic Intracranial Hypertension? Another analysis found that intracranial pressure seemed to drive headache and visual changes more than pulsatile tinnitus itself, suggesting the tinnitus in IIH may have a partially independent mechanism.12PubMed Central. Pulsatile Tinnitus as the Primary Symptom in IIH: A Distinct Clinical Entity
The practical takeaway is straightforward: if your pulsatile tinnitus appeared with a cold and goes away with the cold, IIH is not the concern. If the sound persists long after you have recovered, or if you also experience worsening headaches, blurry vision, or visual obscurations (brief episodes where your vision dims, especially when bending over), bring it up with a doctor. IIH is treatable, and early detection can protect your vision.
Practical Signs That Suggest a Doctor Visit
Not every episode of pulsatile tinnitus during a cold requires medical attention. But certain patterns raise the stakes enough to warrant an evaluation. Consider seeing a doctor if:
- It persists beyond three weeks: Cold-related Eustachian tube dysfunction should resolve within about two to three weeks. If the pulsing continues well past that point, something else may be going on.
- It is one-sided and constant: Unilateral pulsatile tinnitus that does not fluctuate with congestion is more concerning than bilateral or intermittent symptoms that shift with head position or nasal stuffiness.
- You can hear it objectively: If someone else can hear the sound when they put their ear close to yours, or if a doctor can hear it with a stethoscope, that suggests a vascular source rather than a pressure-change issue.
- You have associated neurological symptoms: Headaches that worsen with straining, visual changes, dizziness, or facial numbness alongside pulsatile tinnitus point toward vascular or intracranial causes that need imaging.
- You have cardiovascular risk factors: A history of high blood pressure, high cholesterol, or smoking raises the likelihood that the sound comes from atherosclerotic narrowing of an artery rather than from temporary congestion.
When imaging is indicated, clinicians typically start with CT angiography or MR angiography to look at the blood vessels around the ear and skull base. The choice of study depends on what the clinical suspicion is. For venous causes, MR venography is more revealing; for arterial stenosis or fistulas, CT angiography tends to give sharper detail.
Tumors as a Rare Cause
Among the less common structural causes of pulsatile tinnitus are glomus tumors, small vascular tumors that grow in the middle ear or along the jugular bulb. Glomus tympanicum tumors are benign but highly vascular, and they sit close enough to the eardrum that the blood flowing through them produces an audible pulse. In one surgical series, pulsatile tinnitus was the primary complaint in about 62 percent of patients with glomus tympanicum tumors, and it resolved immediately after surgical removal in every case.13PubMed Central. Treatment Outcomes of Patients with Glomus Tympanicum Tumors Presenting with Pulsatile Tinnitus These tumors are rare, grow slowly, and are often visible as a reddish mass behind the eardrum on routine otoscopy. They are not something a cold would cause, but they are worth mentioning because they are a treatable cause of pulsatile tinnitus that sometimes gets discovered only because a patient comes in about a pulsing sound they initially assumed was from congestion.
The Emotional Weight of Hearing Your Own Pulse
Even when pulsatile tinnitus is temporary and benign, it can be surprisingly distressing. The rhythmic, inescapable nature of the sound makes it harder to tune out than steady background noise. You cannot turn away from it, and lying in a quiet room at night can turn each heartbeat into an intrusive thump. For people whose pulsatile tinnitus is chronic rather than cold-related, the psychological toll is significant. A study of pulsatile tinnitus patients found that roughly 46 percent reported moderate to severe depression and about 37 percent reported moderate to severe anxiety.14PubMed Central. More than just noise: Association of pulsatile tinnitus with anxiety, depression, and reduction of quality of life Higher tinnitus severity scores were closely linked to both conditions.
For a cold-related episode, knowing that the sound has a clear, temporary cause can reduce the anxiety considerably. But anxiety itself can worsen the perception: when you’re stressed or hypervigilant about the sound, you notice it more, which makes you more anxious, which makes you notice it more. Breaking that feedback loop with masking sounds, distraction, and reassurance that the cause is benign is often the most effective short-term strategy. If you find yourself catastrophizing about the sound or losing sleep over multiple nights, talking to a doctor can help even if the underlying cause is just a cold.
Colds, Ear Infections, and Fluid Buildup
A complication worth knowing about is the progression from a cold to acute otitis media, a middle ear infection. Colds are the leading trigger for middle ear infections, especially in children but also in adults. When Eustachian tube dysfunction prevents the middle ear from draining, bacteria from the nasopharynx can colonize the trapped fluid, producing a full-blown infection with pain, fever, and sometimes hearing loss. That infected, fluid-filled middle ear is an even better conductor of vascular sound than a merely pressurized one, so pulsatile tinnitus can intensify if a cold progresses to an ear infection.
The inflammatory process in the middle ear also involves the release of growth factors that increase vascular permeability, encouraging more fluid to accumulate and more blood vessels to form in the inflamed tissue.3Wiley Online Library / The Laryngoscope. The role of vascular endothelial growth factor and vascular stability in diseases of the ear This thickened, vascularized tissue in the middle ear can persist even after the acute infection resolves, creating a period of weeks where sounds remain muffled and the pulsatile quality lingers. If you develop ear pain, fever, or a significant drop in hearing during a cold, the situation has moved beyond simple Eustachian tube dysfunction and may benefit from antibiotics or closer monitoring.
Repeated bouts of otitis media can occasionally lead to chronic middle ear effusion, where fluid sits in the middle ear for months. In those cases, pulsatile tinnitus can become a semi-permanent companion until the fluid is drained, sometimes requiring a myringotomy (a small incision in the eardrum) with or without tube placement. This is more common in children than adults, but it does happen in adults with anatomically narrow Eustachian tubes or those with allergies that keep the tubes chronically inflamed.
